Published in the European Heart Journal Case Reports, the authors present a case of a patient who presents with a large expanding pseudoaneurysm (7 cm × 5 cm). The aetiology of this pseudoaneurysm was iatrogenic in nature, secondary to previous endovascular interventions (PCI). The patient presented with haemopericardium and haemodynamic instability after saphenous vein bypass grafting. A pseudoaneurysm rapidly expanded from 5 cm to 7 cm over the follow-up period producing compressive mass effect on the lateral right ventricle with transient haemodynamic instability.The patient’s declining clinical condition did not warrant a redo thoracotomy and sternotomy, so an endovascular approach was deemed to be the best treatment option.Learning points:-- In the setting of venous grafts to coronary vessels, a pseudoaneurysm arising from the graft itself remains to be a rare complication but certainly needs to be addressed if clinically symptomatic.- The use of endovascular embolization techniques is indeed a technically viable alternative with positive outcomes for treatment of specific cases of haemopericardium without the need for thoracotomy and sternotomy.Read in detail about the case here: https://pxmd.co/LMhHA
